8. Catillaria tricolor (With.) T. Fries. 
Thallus whitish to ash gray, minutely granulose, KHO+yellow, Ca(ClO).—; apo- 
thecia minute, sessile, the disk brownish, flat and with a thin, paler, pulverulent mar- 
gin, later becoming darker, the margin disappearing; epithecium subgranulose, pale 
brownish; thecium 56 y» high, colorless; paraphyses subcoherent, capitate at the 
brownish tips; hypothecium colorless; asci clavate; spores bilocular, oblong, 9 to 12 « 
long, 3.5 to 4 » thick, some slightly curved, others apparently simple. 
On various barks. Tuckerman distinguishes a variety atlantica ‘‘with spores 
scarcely other than simple,” from variety pacifica, with typical spores and a decussating 
black hypothallus. Santa Cruz Mountains, the variety pacifica, Herre, and Alameda 
County, Gray. In the Santa Monica Mountains both varieties occur on the same 
piece of bark.

This is the forma vulgaris of authors. On slate rock in the Santa Monica Range,
